IMIROVEMENT IN GAS-REGULATORS.

IO ALL WHOM IT MAY CONOERN:-

Be it known that I, H. GENGEMBRE HUBERT, of the city of New York, county and State of New York, have invented certain Improvements in Gas-Regulators; and I do hereby declare that the following is a full and exact description thereof, which.will enable others skilled in the'art to make and use the same, 'reference being had to the annexed drawings, in whichl Y Figure 1 is a sectional elevation of my improved'gas-regulator through the line z e', and

Figure Zisa horizontal section of the same through :t x.

This invention relates to an improved gas-regulator or pressure-governor, constructed as hereafter described, in which the regulating-valve is moved by a multiplying-lever, acted upon bythe deflection of a metallic partition.

Description.

A is'the body of the instrument, which may be made of any convenient size, and of proper shape for having' a large surface. B is the valve-box, in which is fastened the valve-seat vK. S is the inlet for the gas, and Tis the outlet for the gas. Gis a thin partition'or false lid, made of metal, of papier mache, vulcanized rubber, or any material having enough'rigidity to remain in position, and yet enough flexibility to yield alittle under the pressure ofthe gas or the weight of the Weights W. The metallic diaphragm Gis soldered or otherwise fastened tight to the body A of the instrument. L is` a lever, having its fuleruni ou a spring-piece, P, which is riveted at one end to the body A of thc instrument, and by means of the screw D and key F, the fulcrum of the lever L can be at any time adjusted nearer or further from the diaphragm G. E is a link connecting the centre of the diaphragm G tosthelever L, at a point not very distant from the fulcrum thereof. At the other end of the lever L, at a greater distance from the link E than there is from E to the fnlcrum, the conical valveVis suspended by a proper link, so that the least variation in the position of the lever, caused by the deeetiou-of the diaphragm at the point E, will cause a great variationvin the position of the valve V. His the top, placed over 4the instrument to protect the diaphragm, and I is the lid, which can be removed to cha-nge the weights W.

I Operation. I i v The pipe S being vconnected with the gas-supply pipe, and the pipe T with the gas-consuming pipe, the I weights arercgulated according to the pressure of gas in the supply-pipe, and by lighting the maximum and theminimum number ofburners in the consumcrs pipe,'the proper position of the valve is regulated by altering the fulcrum of the lever L by means of the key F and screw D.

I claim, in instruments for regulating the pressure of gas or 'vaporsfor illuminating purposes- 1. The use of a metallic diaphragm.

2. The combination of the diaphragm G, link E, lever L, and valve V, arranged substantially in tbe manner set forth.

3. Making the fulcrum of the lever L adjustable from outside the instrument bymeans ofa screw, D,

arranged as described, or any mode substantially the same. l

4. The use of a lever for multiplying the sensitivencss of .a gas-regulator, by increasing the throw of the 'alve thereof.
